Abstract
With the increasing utilization of cardiac rehabilitation in clinical treatment and prognosis for patients with cardiovascular diseases, exercise training has become a crucial component. High-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) are commonly employed in rehabilitating patients with cardiovascular diseases.
Introduction
The incidence and mortality of cardio vascular diseases (CVD) have been steadily increasing over the years [1]. According to a study on the global burden of cardiovascular diseases and risk factors, the total incidence of cardiovascular diseases has risen from 271 million in 1990 to 523 million in 2019.
Methods
The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines were followed for the methodology of this review (S1 File). The complete protocol of this meta-analysis was uploaded and registered on the PROSPERO platform with the registration number:CRD42024532872.
Results
A total of 1432 articles were searched, and after repeated checks, 1112 were retained. Subsequently, the articles underwent pre-screening by reading the title and abstract.
Discussion
In this systematic review, we included 22 randomized controlled trials involving a total of 1364 patients and found that HIIT had better effects on improving PeakVO2, 6MWT, and PHR than MICT in patients with coronary artery disease. However, there was no significant difference in LVEF, LVEDV, and SBP.
Conclusion
The results of this systematic review showed that compared to MICT, HIIT had a greater improvement on PeakVO2 among CAD patients. Furthermore, HIIT seemed unaffected by intervention duration, exercise mode, frequency or exercise session when it came to enhancing PeakVO2.
